OUTBOARD-MOTOR.

Application filed February 10, 1916. Serial No. 77,504

To all wlw/m t 'may concern.' n

Be it known that I, l RICHARD B. OWEN, a citizen of kthe United States,residing vat lVashington, in the District of Columbia, have inventedcertain new and useful Improvements in Outboard-Motors, of which thefollowing is a specification.

An object of my invention is to provide an outboard motor arranged to becapable position in which the propeller is out of the water, withoutdetaching the motor 'from the boat, with means by which the desiredmovement may be given to the motor.

A further object-is to provide a mounting by which the motor may haveswinging movement to accomplishthe purpose hereinbefore set forth andwhich mounting is so arranged that various adjustments may be made toaccommodate the motor to different angles of boat stern, and further todispose the parts in such a relation that when the motor is brought tothe raised position, it will be automatically held through its owncounterbalanced weight until manually returned to the operativerelation.

Yet another object is to form the mounting in such a manner that certainof the parts may shear or cut off in case of an obstruction beingencountered by the propeller and damage to t-he main parts of theoperative structure will b'e precluded.

With other objects in view, which will be referred to, my inventionconsists in still other novel features of construction and oombinationofparts which will be hereinafter referred to and pointed out in theclaims.

the modification of certain of the parts illustrated more particularlyin ig. 3.

In the presentadaptation of my invention, the motor or power unit isillustrated as be- 1ng of the two -cylinder opposed type in which thecylinders 1l are disposed on opposlte sides of the crank case. The crankshaft of the engine is extended down through the housing v2 to a gearhousing 3 from which the .propeller 4 is driven, and a fuel tank 5 1sdlsposed around the upper bearing of the crank shaft, lthe Hy wheel 6being placed to revolve above this tank if desired. Cooling water to thecylinders is supplied by a pump 7 through the tubing 8, or in any otherdeslred manner, and it will be understood that variations of the motorstructure in any member might be resortedto and that the be made ofthesingle cylinder type if desired.

The motor brackets 9 and`10, the details` of construction of which arebetter illustrated in Fig.14, are provided with right angularly disposedorifices 11 and 12 through which the bolts 13 or other suitablefastening means may be passed to be secured in the cylinders 1 of 'themotor and toI thus mount the motor brackets rigidly in place. Thebrackets 9 arms 14 at an angle preferablyv approxiately midway betweenthe angular position of the orices 11 and 12, and are widened out intodisk forms 15 which disks are disposed around the central openings 16.The boatbracket 17 is of substantially standard form in so far as theclamping screws 18 and the main parts of the structure are concerned,and around the pivot bearing 19 on the mounting arms thereof, disks 20corresponding tothe disks 15, are provided.

In the mounting of the motor on the boat bracket 17, the motor brackets9 and 10 will be secured rigidly on the cylinders in .the manner.hereinbefore set forth and the mounting arms of the boat bracket 17 arespaced apart a. sufficient distance that the disks 20 of the same willbe received between the disks 15 of the motor brackets. In the presentinstance the orifices 16 of the motor brackets 9 and 10 are screwthreaded and the pivot bolts 21- are passed through the orifices 19 ofthe mountingj arms of the boat bracket and are screwed into the orifices16 to provide a pivotal or hinged mounting and 140,. are extended in thethe gasolene tank between the motor and the boat bracket which willpermit tilting or swinging of the parts'tc the relation illustrated indotted lines in Fig. 1, where the propeller is raised out of the waterto permit the same to be cleared of weeds, to allow the boat to be drawnup on a beach without detaching the motor and for other purposes whichwill be apparent.

In some instances it might be found sufficient to tighten the bolts 21to clamp the disks 15 and 20 in a frictional bearing and thus hold themotor disposed at the proper angle with respect to the boat bracket 17which is secured on the stern of the boat. However, it is desirable thatthe connection between the motor brackets and the boat bracket be a freeswinging pivotal mounting, plurality of orifices 22 through the disks2() at a common radius from the center of the disk, and a singleregistry opening 23 is provided through the disk 15. A pin 24 isprovided to be received through the opening 23 and fitted in one of theorifices 22 to hold the motor in its proper angular adjustment and toprevent displacement of the parts from this adjustment, and if desiredthis same arrangement may be used on each of the motor brackets. It ispreferable that a retaining means 25 be connected with the pin 24 toprevent loss of the same, and if desired the pin may be made of a softbrassv or other metal which will be sheared or cut o' when unusualstrain is placed thereon, as for instance, byv the propeller gearhousing 3 or the propeller striking an obstruction. Where it is desiredto obtain finer adjustments than might be procured through the singleseries of openings 22, a second series of openings 26 may be providedradially around the center of the disk at spaced points between theorifices 22 and it is preferable that these openings be disposed at adifferent radius, therefore, a second o-pening 27 is provided throughthe disk 15 and the pin 24 when inserted through this opening 27 willregister with an orifice 26 and it 1s thus possible to obtain a numberof various angular settings of the boat bracket 17 to accommodate themotor to widely varying angles of boat stern.

The motor when swung to an operative position is disposed with itsweight balancedl past a dead center over the hinged or swinging mountingof the yboat bracket, and for this reason it is desirable that somemeans be provided. to raise or move the motor to a positlon in which thepropeller is out of the water'and in which the parts will take theposition indicated by the dotted lines of Fig. 1. In the presentdisclosure I have shown the strap metalv pieces 28 secured to at spacedapart points to have their upper ends project above the top and for thisreason I have provided a y While I have herein shown of the tank andprovided with the ring openings 29. A cross handle 30 is fitted intheopenings 29 to extend between the members 28 and this handle is thusdisposed at a point that' it may be readily grasped to elevate the partswhile yet in operation or after the motor has been stopped, it beingonly necessary to remove the pins 24 to permit the motor to have freeswinging movement around its points of mounting on the boat bracket 18.

In Fig. 7, I have illustrated the slightly modified form of pin whichmight be used in place of the pins 24 and in this illustration a casing28 is secured to the disk l5 in line with the opening thereof. A pin 29is mounted in this casing and in the opening of the disk 15 and` a coilspring 30 is received around the pin 29 to hold the same normally in aposition of projection through one of the orifices of the diskv 2O ofthe boat bracket, a handle 31 being provided on the pin to permit manualwithdrawal of the same against the tension of the spring 30 from theoperative relation.

In the fitting of the motor to a boat, it will be understood that theboat bracket 17 will be hung over the stern and the clamp screws 18 willbe tightened to secure the bracket rigidlyl in place. By grasping thehandle 30 the motor may be moved around the bolts or pins 21 to adjustthe same to a position that the propeller is working at the proper angleand then by inserting the pins 24 in the registering opening andorifices, the motor brackets will be-rigidly secured against swingingmovement with respect to the boat bracket 17 and the motor will bemaintained in an operative position. As the motor is to be swung to theraised position,

'the handle will be grasped and the pins removed after which the motormay be raised through the handle 29, and also when the propeller or thegear housing have encountered an obstruction and the pins 24 have beensheared,.the motor is left -freeto have swinging movement and maybereturned by the use of the handle 29 to an operative position where itmay be secured in the manner set forth.

and described the motor as mounted to. be capable of swinging or tiltingmovement, it will be apparent that a mounting might be provided whichwould permit the desired raising of the motor to a position withthe-propeller out of the water through a substantially vertical raisingthereof, and in such a structure as this the handle would be alsoadaptable and equally advantageous, further it will be seen 1i beresorted to 1n' the variousparts without 1 departing from t-he spiritand scopeof my invention and hence I do not Wish to be limited to theexact disclosures except for such limitations as may be contained in theclaims.
